CVE-2026-57225: CWE-476: NULL Pointer Dereference in OISF suricata
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. From 8.0.0 until 8.0.6, src/datasets-context-json.c assumes that a configured JSON or NDJSON dataset value_key resolves to a string. A trusted or untrusted dataset or rule feed containing a non-string value for that key can cause a NULL pointer dereference during startup, configuration test mode, or rule reload, crashing Suricata before traffic processing. This issue is fixed in version 8.0.6.
AI Analysis
Technical Summary
Suricata, a network intrusion detection and prevention system, contains a NULL pointer dereference vulnerability in the src/datasets-context-json.c file. From versions 8.0.0 up to but not including 8.0.6, the software assumes that a configured JSON or NDJSON dataset value_key resolves to a string. If a dataset or rule feed (trusted or untrusted) provides a non-string value for that key, Suricata may dereference a NULL pointer during startup, configuration test mode, or rule reload, leading to a crash before traffic processing begins. This issue is resolved in version 8.0.6.
Potential Impact
The vulnerability causes Suricata to crash, resulting in denial of service before it can process network traffic. There is no impact on confidentiality or integrity. The CVSS score is 3.3 (low severity), reflecting the limited impact of availability disruption without further compromise.
Mitigation Recommendations
Upgrade Suricata to version 8.0.6 or later, where this NULL pointer dereference vulnerability is fixed. No other mitigation is necessary as the issue is resolved in the official patch.
